PDF RICE HUSK ASH

Rice Husk Ash Cement Introduction Rice husk ash (RHA) is a by-product from the burning of rice husk. Rice husk is extremely prevalent in East and South-East Asia because of the rice production in this area. The rich land and tropical climate make for perfect conditions to cultivate rice and is taken advantage by these Asian countries. The husk

Further, it is observed that, partial substitution of cement with RHA increases strength in all the concrete mixes. The result indicates higher compressive, split-tensile and flexural strength at 10% partial replacement of fine aggregate with crushed seashells and 20% partial substitution of cement with RHA.

Rice husk ash (RHA) is used as a replacement to cement to produce mortar. The effect of 5, 10, and 15wt% addition to the density and compressive strength of mortar is investigated. It was found that with the increasing addition of RHA causes the decrease of compressive strength and density of mortars. Compressive strength of mortar drops with addition of RHA, from a value of 42 MPa of no RHA
